Abstract: An arc fault circuit breaker assembled such that electrical interconnections, i.e., electrical connections between compartments, are made without disassembling any previously assembled compartment. The arc fault circuit breaker comprises housings having compartments within. Electrically connected components having interconnecting components, i.e., components which provide electrical interconnections between compartments, are disposed within the compartments. The housings are assembled together to enclose the compartments. Interconnecting components within an enclosed compartment extend through openings in the housings to provide electrical interconnections to the next compartment to be assembled. Therefore, no disassembly of the enclosed compartment is necessary to make the interconnections.

Abstract: The cycloalkano-pyridines are prepared by reacting corresponding cycloalkano-pyridine-aldehydes with suitable organometallic compounds or Wittig or Grignard reagents or reacting compounds of the cycloalkano-pyridine alcohols type with suitable bromine compounds, and optionally varying the functional groups accordingly. The cycloalkanopyridines are suitable as active compounds in medicaments, in particular in medicaments for the treatment of hypertipoproteinaemia and arteriosclerosis.

Abstract: Alkoxytriazolinones of the formula (I) ?known for example as intermediates for preparing agrochemically active compounds! ##STR1## wherein R represents an alkyl group, an alkenyl group, an alkinyl group, a cycloalkyl group, a cycloalkylalkyl group, an aryl group or an arylalkyl group, any of which may be substituted, are prepared by reactinga) thioimidodicarboxylic diesters of the general formula (II) ##STR2## wherein R is as defined above and R.sup.1 represents an alkyl group, an arylalkyl group or an aryl group, any of which may be substituted, withb) hydrazine, hydrazine hydrate or an acid adduct of hydrazine.The reaction is conducted i) in the presence of a diluent and, optionally, in the presence of a basic reaction auxiliary, and ii) at temperatures between -10.degree. C. and +100.degree. C.

Abstract: The invention relates to the crystalline form of the hydrochloride of the compound (R)-(-)-2-{N-?4-(1,1-dioxido-3-oxo-2,3-dihydro-benzisothiazol-2-yl)-butyl! -aminomethyl}-chroman, which is present as a stable form at room temperature. The crystalline modification V of the hydrochloride is suitable in particular for the preparation of solid medicaments, in particular of medicaments for the treatment of neuronal degenerations.

Abstract: Method and apparatus for determining the location of a broadcasting station in a local area network communications system such as Ethernet that is arranged in a bus topology. An echo module, positioned at one end of a cable, receives a packet broadcast by a station and broadcasts a distinctive echo pulse on the cable during the interframe gap or at another chosen time. A processor module positioned at a second end of the cable receives the originally broadcast packet and the echo pulse, notes the times of receipt t.sub.1 and t.sub.2, respectively, of these signals, and determines the temporal distance T.sub.1 from the broadcasting station to the echo module by the equationT.sub.1 =(t.sub.2 -t.sub.1 -.DELTA.t.sub.dp)/2,where .DELTA.t.sub.dp is a time delay associated with validation of the echo pulse.
